Grease vs Grease
I have some blue 'marine' grease and one of those Speedplay grease guns for my pedal bodies. Is there anything incorrect about using this type of grease on some bottom bracket bearings -- Campagnolo Ultratorque crank bearings? Or should it be some other type of grease? Finish Line has 'premium grease' or 'ceramic grease', etc. I also have a tube of Park Tool "PolyLube".
I guess I'm asking what type of greases are ok for bearings (versus simpler things like seatposts or pedal threads).

If you ride through wet conditions, marine grease should be an excellent choice. But I'm not going to be the one able to say if it makes you use more effort to pedal the bike over some specialized wonder grease.

It's okay in my opinion. How thick or thin the grease is will be more important. Thick not necessarily better, So any grease that's good enough for automotive or marine use is likely adequate.

Most any grease & occasional service is good.
I used to use boat trailer wheel bearing grease until it occurred to me that I don't ride in the rain.
Synthetic since.

Park has at least 2 versions, not including their anti-seize product:
1. Park HPG-1
2. Park PPL-1

I like Motorex 2000 just because it's the same translucent neon green color of Dura Ace grease. I got a lifetime supply for $24 a couple of years ago:

Bicycle hubs don't require a "space age" type of grease. The grease they had 100+ years ago was adequate if serviced on a somewhat regular basis.
The cheapest automotive wheel bearing grease is more than adequate.
Get a tub of that or if you want to spend more like me, get a tub of synthetic.
It'd be pretty hard for anyone to argue "their grease is better".

It will work fine, but marine grease tends to be very waterproof and quite difficult to clean out when you need to refresh it. This is great in marine applications where there isn’t much dirt, or in Speedplay bodies where you push out the old grease with new, but for other applications you might find the stickiness annoying.

I've got some nice thick gray/blue grease from the auto store that works great. I only use it in big areas because I don't have a gun for it.
Pedro's in a gun for more exact greasing.
I used to have a tube of white silicone grease, the cheap stuff for garage doors, it also was fine.
I think just about anything would work at the low speeds anything on the bike turns.
Maybe avoid vaseline?
Edit to add, if you're selling hubs, a bike branded grease seems to matter to buyers. So resale with Phil's or Park and the items will sell easier, it shows that you care. I don't think it affects the ride.

Speedplay might sue you for using the wrong grease, but the pedals won't care.

Bicycle bearings are not a particularly challenging environment for grease (low speed, low load, low temperature), so just about anything will suffice. If you ride in wet weather a lot, a marine grade grease may resist washing out better than a general purpose bearing grease. I like white lithium grease, largely because the color makes it obvious when the grease has gotten contaminated and needs to be replaced.

I have two types of grease. Shimano Dura-Ace, which I use in wheels and anything I would consider critical (basically just my DA wheels). And some red boat trailer bearing grease, which I use for virtually everything. The wheels are only ridden in good conditions and rolling resistance is the primary concern hence DA. For everything else, low cost and durability are the primary concerns.
